Just swapped out the JL front stage for Focals. 6.5" coax in the doors and 4" coax in the dash both with aimable tweeters and 6.5" mids in rear doors powered by a hifonics Zeus Amp 170watts @2ohms to front and 85watts to mid bass rears. It sounds AWESOME. the clarity, imaging and definition is way way better than the JL's. I am blown away, can not even imagine how good seperates would sound if these sound this great!
